Trenchless culvert relining: alternative to digging, replacing or sliplining old culvert pipes
I have discovered that most of Saskatchewan’s rural municipalities have at least one culvert that’s too expensive to dig up and replace. These culvert pipes are:
- Too deep under the road,
- Hard to access,
- Too big,
- Too long or
- Under a road where the traffic is too high to dig up the roadway and replace the line.
Look at this culvert: 30 feet of soil above the pipe. Digging this up and replacing it would take weeks and tens of thousands of dollars.
Photo: deteriorating culvert in Saskatchewan where the municipality can use Centri-Pipe to reline the pipe instead of digging up the road and replacing the culvert. In this location, there is 30 vertical feet of soil above the culvert pipe and it is not feasible to dig and replace. APM Centri-Pipe is the best option to save this culvert.
CENTRI-PIPE: PROVEN PIPE RELINING – trenchless alternative to culvert replacement and pipe sliplining
Culverts that were constructed during the 1980s are deteriorating and most are scheduled for replacement. Martech and AP/M Centri-Pipe want to introduce you to a proven culvert relining process that will save money and time for your department.
Centri-Pipe pipe relining has major benefits for small municipalities:
- Centri-Pipe is a trenchless solution – DO NOT dig up your roadway
- Reline your culvert pipe in a fast 1 to 3 day process
- The new lining gives full structural support
- Adds at least 40 years to your culvert’s service life (engineer says 70-100 years)
- Works with culverts 30″ to 120″ pipe diameter
- Almost zero loss of water flow rate after relining
- Environmentally friendly, no toxins in the mix
- Reline culverts all year round without stopping for winter
